I think he would work better with a 5 that can clear space and set big screens. They should have tried to get Steven Adams.
The Grizzlies had to bench Steven Adams in round one because the TWolves ran him off the court. Plus on offense if Adams is out there Luka now has another defender waiting for him in the lane every single time now. The Mavs had DeAndre Jordan , that’s who they traded for Porzingas, if they wanted a big dude to set screens and rebound, they already had him on the team.
For the last few years you’ve seen teams go five out and attack even the best defensive big guys, the Mavs themselves have ate up Goebert and Ayton in this playoffs by making them guard the 3 point line the whole time. Teams would put Adams and Doncic in pick and rolls over and over again.
Porzingas didn’t work out but it wasn’t because they weren’t trying to build around Luka. I think they just weren’t thinking unconventionally enough, in retrospect they should have been in the market for another wing and been willing to play even smaller and force teams to adjust to them.
